摘要： A process for producing an alkylated organic compound via alkylation and/or transalkylation in which an organic feedstock is contacted with an organic reactant in the presence of a catalyst under conditions such that components of the organic feedstock react with the organic reactant to form an alkylated compound. The catalyst comprises a molecular sieve having alkylation and/or transalkylation activity and contains, after calcination, between about 250 and 20,000 ppmw ammonium ions, calculated as (NH.sub.4).sub.2 O on a volatiles-free basis. In two preferred embodiments of the invention, the catalyst is employed, respectively, in the alkylation zone of a process for producing cumene via the alkylation of benzene with propylene and in the alkylation zone of a process for producing ethylbenzene via the alkylation of benzene with ethylene.
